New Revision: 227271
URL: http://llvm.org/viewvc/llvm-project?rev=227271&view=rev
Log:
Added test case to make sure we don't regress on settings breakpoints by selector and with the various partially specified ObjC specified breakpoints.
This test tests the equivalent of:
breakpoint set --name count
breakpoint set --selector count
breakpoint set --name isEqual:
breakpoint set --selector isEqual:
breakpoint set --name "-[MyClass(MyCategory) myCategoryFunction]"
breakpoint set --name "-[MyClass myCategoryFunction]"
breakpoint set --name "[MyClass myCategoryFunction]"
